This is definitely the cutest thing we've seen all day. Rumer Willis took to social media today to celebrate Throwback Thursday with a too cute Instagram of herself as a little girl, and she looks so much like her actress mom Demi Moore.

In the black and white snap, a young Rumer poses for the camera in a sleeveless dress, her little arms crossed behind her back and her brunette hair artfully blowing in the wind. Willis gave the photo a simple caption, appropriately writing: "#tbt."

But this isn't the first time the star has shared an adorable picture from her childhood. A few months ago, she celebrated #NationalSiblingsDay with a hilarious 'gram of herself alongside her siblings Tallulah and Scout and famous mom. And back in February, she melted our hearts with a photo of her and her actor father Bruce Willis on the set of one of his movies.

One thing's certain: Rumer was certainly a darling youngster.
